1 Claim.

Vaction cushioned Wheels,

And another object is the provision of a skate withva sub-body.

The manner in which the above and other objects are efectuated will be apparent from a reading of the specification taken in connection .with the accompanying drawing, in which:

Figure 1 is a side elevation of the skate;

Figure 2 is a front elevation thereoffV Figure 3 is a bottom plan view of the front truck section;

Figure 4 is a sectional view, partly in elevation, of the front truck, and

Figure 5 is a sectional view taken on the line 5-5 of Figure 1. f

, -Similar numerals refer to similar parts throughout the several views.

Referring now to the drawing the numeral I8 refers to a skate having a foot plate I LI, the forward end of whichvhas arranged thereon a, pair of clamps I2 and I3, which are preferably of any conventional type, with screw threaded portions I4 and I5 being arranged in the retainer threaded collars I6 and I1.

Positioned at the rear end of the foot brace is a heel supporter I8.

Between the front and back trucks I9 and 20, and attached thereto, is a brace or under plate 2|. The brace is attached to the front and rear trucks by means of the bolts, or rivets, 22 and 23 and the lugs 24 and 25 extending from the rear and front trucks, respectively.

The two trucksV are similar in construction and, therefore it is deemed suiiicient that only one of them be described. ,c f

The wheels 29 and 39, of the front truck are Vpositioned on an axle 3| which works in a bearing housing 32, the wheels being held in position through means of the nuts. 33 and 34.

Referringr particularly to Figure 4, it will be apparent that the truck is fastened, by means of the rivets 35 and 38 and 31 to the foot plate II. This is a rigid connection but, in order to provide ilexibility between the foot plate and the surface to be ridden upon. there is provided a movable arm 38, having a ball 39 at its upper end which is positioned in a socket 48.

Intermediate of its ends. the arm 38 is en- (ci. 28o-11.28)

' 2 larged for the reception of coil springs 42 and 43, the opposite ends of which rest in a recessed part 44 of the front truck.

The arm 38 has a bight portion 4I from which depends an oblique shank portion 45 which carriesat its terminal the bearing housing r32 ad which has an opening 46a for screw 46 which has a ball 41 at its one end, the ball fitting in a socket 48. This socket is formed by a housing 49, which preferably, is an integral part of a standard 58. Y

VAt the lower end of the housing 49, which is angular, there is positioned an insert cap 5I. which has an opening therethrough for the reception of a tension adjusting screw 52, and at the inner end of the screw is a recessed plate 53 which will receive the ball 41. Above the ball 4l is a, similar recessed plate 58 and above the plate 58 a spring 59 rests against the top of the housing 68. v

In operation it will be seen that when an obstacle, such as a bump, or depression, in the surface is nmet'. by the front wheel it will give while acting against the springs 43 and the spring 59 will allow upward movement of ball 41 and screw 48. When turning, the balls/39 and 41 will render unusual flexibility to the skates.

While IV have illustrated and described the preferred embodiment of the invention it should be understood that various'changesmay be made within the scope of the appended claim.

What I claim is:

A skate comprising a foot plate. a rear truck assembly supporting said foot plate and con pri-sing a hanger having a, rearwardly extending portion adjacent the plate provided with a downwardly directed socket, a hollow dependent housing at the lower end of the hanger having an opening in the rear wall thereof, an arm having an enlarged laterally extending portion intermediate its ends, the ends of said portion disposed at laterally opposite sides of the arm, a compression spring interposed between the rear of the hanger and each of said ends of said enlarged portion, a ball formed at the upper end of the Y arm and. adapted to be received in said socket, an axle journalled in the lower end of said arm, wheels mounted at each end of said axle, a rod threadably mounted in the arm adjacent the lower end thereof and extending forwardly through the opening in said hollow housing, a ball formed at the forward end of said rod and positioned in said housing, aV spring-pressed upper plate in said housing having a socket for receiving the ball therein, a, like lower plate in said bly and a rod interconnecting the rear and front hangers.
